Hi,

I am planning to buy your PH sensor (
http://wiki.seeedstudio.com/Grove-PH_Sensor/) and run with 3.3v. According
to the wiki, it requires 5V but according to schematic, it is using LDO 5v
to 3.3v so I am not sure if I can use with 3.3v or not. Can you help to
confirm so that I can proceed buying it? Thanks.

Thanks,
Minh

Hello,

Pls refer to the datasheets of XC6206, it says:
 The output voltage when “VOUT(T)+1.0V” is provided at the VIN pin while maintaining a certain IOUT value.)

That means to gain a stable output voltage of 3.3v, the input voltage must be over 4.3v.
Maybe it can work when you supply it with 3.3v, but I can not promise anything.
Thanks
